SPECIFICATION forming part of Letters Patent No. 511,622, dated December26, 1893.

Application tiled March 25, 1893.

To @ZZ whom. it 11n/Cty concern:

Be it known that we, GEORGE I. JORDA and GOTTLIEB JORDA, of the city,county, and State of New York, have invented a new and Improved RotaryEngine, of which the following is a full, clear, and exact description.

Our invention relates to improvements in -rotary steam engines; and theobject of our invention is to produce a rotary engine of greatsimplicity and of cheap construction, which is adapted to utilize to itsgreatest eX- tent the expansive force of the steam, and which isarranged so that the steam will act continuously to turn the piston.

To this end our invention consists in certain features of constructionand combinations of parts, as willbehereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a side elevation of the engine embodying our invention. Fig.2 is a front elevation of the same. Fig. 3 is an elevation of the enginewith the cover or one side of the cover removed. Fig. 4 is a brokeninside i f elevation of one part of the case, showing the piston in adierent position.

the opposite portion of the case.

arrangement of steam chambers and ports therein. Fig. 5 is a detailcross section on the line 5-5 in Fig. 4. Fig. 6 is an elevation, similarto that shown in Fig. S, but with the Fig. 7 is a silnilar view to thatshown in Figs. 3 and 6, but with the piston in still another position.Fig. S is a cross section on the line 8-8 in Fig. 6. Fig. 9 is a crosssection on the line 9 9 in Fig. 3. Fig. 10 is an inside elevation ofamodied form of the engine which is adapted for use as a marine engine.Fig. 11 is an inside elevation of one part of the case shown in Fig. 10.Fig. 12 is an inside elevation of Fig. 13 is a cross section on the line13-13in Fig. 12; and Fig. 14 is a detail cross section of the piston,the section beingtaken on the line 14--14 inFig. 10.

vThe engine is provided with a stationary case made in two parts 10 and11, the latter being merely a cover for one end of the case, and theseparts are'heldtogether by bolts 12 and are provided in theiradjacentfaces with Serial No. 467,561. (No model.)

a suitable packing ring to prevent the escape of steam. The case ispreferably of cylindrical shape eXteriorly, and must be interiorly; itis supported on a suitable base 13 which has upwardly extending curvedflanges 14 to lit the curved sides of the case to which the flanges aresecurely bolted. lVithin the case is a rotary piston 15 which turnssteam tight in the case, and to this end the piston has in its face apacking ring 16 which fits snugly against the inner face of the case.The piston is secured to a shaft 17 which projects through the ends ofthe case, being held in suitable packing boxes 18 and from which powermay be taken in the usual way.

The engine, as shown, is a duplicate engine; that is, it is providedWith similar ports and chambers on each side ofthe piston, with similarports and chambers in each end of the case, and with an inlet andexhaust on each side, so that in running the engine either side may beused, butr both are not used together. One side only of the engine willbe described below, and as the other side is similar, it is needless todescribe it.

The engine is provided on each side With an inlet pipe 19 which connectswith aport 2O which leads to a curved steam chamber 21 and vthisconnects by means of a channel 22 with a similar chamber 23, thesechambers being arranged in diametrically opposite sides of the case andin each end, the chambers having an inclined back Wall so that they aredeep at one end and shallow at the other. The chambers 21 and 23 are indirect communication, as illustrated in Fig. 4, and their curvatureconforms to the curvature of the piston, so that the chambers areadapted to register with similarly shaped chambers 24 in the face of thepiston and on diametrically opposite,y

sides thereof. The pitch of the back walls of the chambers 24 isopposite, however, to that of the chambers 21 and 23, and the steam inthechambers 2l and 23, striking the abutment formed by the wall at thedeeper ends of the chambers 24, serves to turn the piston in thedirection yot the arrow in Fig. 3.

In the face of the piston 15, adjacent to the deeper ends of thechambers 24, are channels or ports 25 which are adapted to connect Withchambers 2G in the stationary case end and thus convey steam to the saidchambers so IOO that it may act on similar chambers 27 in the piston.The chambers 26 and'27 are shaped with relation to each other, exactlylike the chambers 21, 23 and 24, and are placed concentric to the outerchambers, and a double 'set of chambers is thus provided so that thesteam will have a double action on the piston. Near the end of one ofthe chambers 26 in the stationary part of the engineV is an exhaustopening 28 leading outward to a port 29 which connects with the exhaustpipe 30. When the steam enters through the pipe 19 and port 20, it fillsthe chambers 21 and 23 and passing through the channels 25 enters thechambers 26 and 27, where it expands and, acting on the walls at thedeeper ends of the chambers 27, causes the piston 15 to start in thedirection of the arrow in Fig. 3.

The fiat faceof the piston will be opposite the -exhaust port 28 so asto close it, and as the Vpiston starts the chambers 24 are broughtoppositethe chambers21 and 23 so that the steam expands in the chambers24 and, acting against their walls atV their deeper ends, continuesto,turn the piston in the direction indicated, afterwhich the innerchamber 27 passes'opposite the exhaust opening 28 and the steam exhauststhrough said opening and` through the port 29 and pipe 30. It will thusbe seen that the steam acts longitudinally in the chambers27 and 24, soas to be exerting force constantly on the piston and the latter issteadily turned and exhausts every time oneofthe chambers 27 passes theport 28.

Asshown in Figs. 10 to 14, the engine is of a simplev formfand istherefore better adapted forlmarine purposes, the engine here shownbeing .a single engine having a pair of steam chamberson each side ofits piston. The e'ngine is provided with a case consisting of two parts,31-and 32, substantially like the parts lOfand l1 already. described,except that the chambers and ports are differently arranged,

yand the case is. held in a base similar to the onealready referred to.In the part 3l is held `the inlet pipe 42 which connects with one of thechambers 40, in the case, which chambers will be described below.

The chambers 40 are of segmental shape, and are arranged indiametrically opposite sidesiof` the case, the chambers havinginclined`back walls, so that they are deep at one end and shallow at the other,and the two chambers areV connected by a channel 41, so thatboth will befilled with steam at the same time.

The piston 37 which rotates in the case, is provided on one side withchambers 43, which areproduced in one face so as to register withthechambers4O in thev part 31 of the case, and these chambers are shapedlike the chambers40, except that they have opposite inclinations, andthe steam which expands in the chambers 40 and 43, acts on the walls atthe deep ends of the latter chambers'so as to revolve the piston. On theopposite side of the piston are similar chambers 36, from the shallowends of which extend ports 39, these leading transverselyy through thepiston so as to connect with the chambers 40 and provide for the exhaustas described below.

The chambers 36 are adapted to register With the chambers 38 in the part32, which chambers are like the chambers 40 already described, and whichenable the steam to expand so as to act on the wide end walls of thechambers 36, and assist in propelling the piston. Opening radiallyoutward from the deeper ends of the chambers 36 are ports 35, which areadapted to register Vwith the side port 34 in the end 32 of the case,and this port connects with an exhaust pipe 33; The steam then willenterthe pipe 42, and expandf ing in the chambers 40 and 43, will,propel the piston, and as the ports 39 come opposite the chambers. 40,the expanded `steam will pass out through the ports to the chambers 36Vand 38, and when the ports 35 ofthechambers 36 come opposite thechambers 38, thelengine will exhaust.

Having thus described ourinventiomwe claim as new and desire to secure`by Letters Patent- 1. Arotary engine, comprisingl a stationary casehaving Vsteam chambers in its end walls,
